Ah yes, the infamous Dr John Coleman aka (if we are to believe Eustace Mullins (or his editor) in the item linked below) alias John Clarke "and likely one Joseph Pavlonski, of Russian Khazarian origin":

Is/was "Coleman" an operative or just uncontrollably imaginative? In his book he claims that the Beatles' songs were written by Theo Adorno (died 1969). LOL!:

"...Following the Beatles, who incidentally were put together by the Tavistock Institute, came other "Made in England" rock groups, who, like the Beatles, had Theo Adorno write their cult lyrics and compose all the "music."..."

... or is this just another case of where an internet ocr-only pdf may not actually reflect the original item as published on paper....?

In light of acquaintance with the above extract you may be better placed to assess the plausibility of this book's contents, whether or not you agree with Mullins' remarks in the above link.

As for the authorship of the Beatles songs and music, take a look at Hunter Davies' 1968 "The Beatles - The Authorized Biography" and see if you can find anything at all to contradict the record that the group was organic in origin and of native genius.

It is of course entirely another matter whether 'Beatlemania' was later used as an engine of social conditioning.
